A while back I posted
a write-up on the vintage
Alliance Model U-100 Tenna-Rotor that I installed in the garage
attic with a Channel Master CM5020 VHF / UHF / FM antenna atop it. There are not
many television antenna manufacturers around anymore; their numbers have been decreasing
continually due first to the advent of cable-delivered TV and now with Internet-delivered
TV. The "cord-cutter"
movement is helping to give over-the-air television broadcasting a rebirth due to
the outrageous cost of subscription programming. Anyone contemplating installing
a television antenna today has the same concerns as those back in 1959 when this
Channel Master advertisement appeared in Electronics World magazine - gain, directivity,
bandwidth, ruggedness, how high to mount it, how to mount it (tower or pole), whether
to use an antenna rotator, and transmission cable type. One new issue not normally
present then is whether your community association (if one exists) allows or controls
size and mounting height of your outdoor antenna.
Channel Master Ad
 Channel Master is telling the T-W story
to almost every family in the United States with the Most Spectacular Antenna Promotion
of all time!
T-W
The Best of Antennas Delivers this Best of Promotions!
To help you sell more antenna replacements, Channel Master commercials will be
broadcast from coast to coast by 4 of America's most popular TV shows over the entire
NBC and ABC networks - 210 TV stations.
In addition to this full network coverage, 2 powerful national magazine campaigns
will put the T-W story into 17 million homes... many of them right in your community.
These ads are aimed at telling consumers that their antenna installations are
becoming old, worn out, obsolete, and that for the best possible TV reception they
should replace their antennas with the T-W. This campaign has been designed to create
new business for you by making the TV family T-W conscious.
 Only Channel Master Gives the Dealer this
Kind of Support!
Now meet the real star of the show...
Three years ago. Channel Master developed the Traveling Wave antenna. This breakthrough
in antenna design was so revolutionary... so far ahead of its time... that modern
science has not yet been able to produce a comparable antenna.
Here's why other antennas simply cannot equal the powerful performance of the
Traveling Wave.
The T-W antenna, featuring the Traveling Wave principle, looks and operates differently
from other antennas. All but one of its elements are driven. No conventional dipoles
are used - only "hairpin" or "fat" dipoles, and a revolutionary new Controlled Impedance
Dipole. The 2-stage phasing harness... the critical lengths and angles of the elements...
the folded reflector... all combine to deliver these unique Traveling Wave advantages:
• Ideal phase relationships on all channels
• Optimum impedance on all channels
• Equal flow of current in all dipoles on all channels
• Fullest use of transmitted energy on all channels
As a result, the T-W brings your set miles closer to the TV transmitter, providing
the highest gains and highest front-to-back ratios ever achieved in a broad-band
antenna.
The T-W is the stand-up-and-take-it antenna!
The T-W is as rugged as it looks. When you install the T-W, you know this hefty
performer is up to stay. It is, without a doubt, the strongest antenna ever built.
Here's why:
"Twin Truss" Construction
All elements and crossarm are made with "twin truss" design. The truss is a basic
construction form used in bridges, airplane wings, and wherever high strength and
light weight are required. This "twin truss" design makes each T-W element more
than 5 times stronger than an ordinary dipole in its ability to withstand the heaviest
wind and ice loads.
Ruggedized Mast Bracket
Heavy-duty U-bolt grips the antenna to the mast. Twist-proof construction. 4
rivets secure the bracket to the mast.
Ruggedized Elements
Seamless 1/2" dia. sleeves, seamless 1/2" dia. U-bend... 20% heavier wall thickness
than regular antenna construction.
"Line-Lok" Absorbs all transmission line tension. Can't tear at terminals.
Weatherproof Harness
Extra-thick 1/4" virgin polyethylene insulation protects impedance and electrical
efficiency against salt air, rain, and ice.
Massive, Heavy Duty Insulator Moldings
The T-W has consumer recognition and acceptance!
Millions of consumers, including those in your own area, recognize and ask for
the Channel Master brand name. Continuous full-scale advertising campaigns, local
advertising, newspaper mats, window displays, streamers, and other advertising aids
have made the American consumer T-W conscious. The Channel Master T-W out-sells,
out-performs, out-lasts every other all-channel antenna. That's why this premium
quality product is still the star of rooftop America... and a most profitable experience
on the part of the dealer and the consumer alike.
